RESUMEN
Background and Objectives: Rheumatoid factor (RF) and anti-cyclic citrullinated protein (anti-CCP) have been used to improve the diagnosis and prognosis of rheumatoid arthritis (RA). However, their association with RA disease phenotypes, individually and in combination, is not well studied. The aim of the study was to compare patients' and disease characteristics, activity and severity in double seronegative (DNRA), single seropositive RF, single seropositive anti-CCP and double seropositive (DPRA) patients. Methods: Adults subjects with RA from Egyptian College of Rheumatology (ECR) database who had RF and anti-CCP results available were included. Demographic, clinical features, disease activity score 28 (DAS28), Health Assessment Questionnaire (HAQ) and laboratory data were collected and compared among different RA groups. Results: 5268 RA patients with mean age of 44.9±11.6 years, and 4477 (85%) were females. 2900 (55%) had DPRA, 892 (16.9%) had single positive RF, 597 (11.3%) had single positive anti-CCP while 879 (16.7%) had DNRA. Patients with DPRA had significantly high percentage of metabolic syndrome (19.3%, P < 0.001), and functional impairment using HAQ (P = 0.01). Older age (RRR [relative risk ratio]: 1.03, 95%CI: 1.0, 1.0, P = 0.029), greater DAS28 (RRR: 1.51, 95%CI: 1.2, 1.9, P < 0.001), higher steroid use (RRR: 2.4, 95%CI: 1.36, 4.25, P = 0.002) were at higher risk of DPRA while longer disease duration (RRR: 1.08, 95%CI: 1.01, 1.16, P = 0.017) and fibromyalgia syndrome (RRR: 2.54, 95%CI: 1.10, 5.88, P = 0.028) were associated with higher odds of single positive RF status. Conclusion: Dual antibody-positive status has higher disease activity and severity, and higher chance of development of metabolic syndrome; highlighting the implicated role of inflammation, atherogenesis and cardiovascular disease risk in RA.
RESUMEN
Sjögren's disease (SjD) is a systemic autoimmune exocrinopathy with key features of dryness, pain, and fatigue. SjD can affect any organ system with a variety of presentations across individuals. This heterogeneity is one of the major barriers for developing effective disease modifying treatments. Defining core disease domains comprising both specific clinical features and incorporating the patient experience is a critical first step to define this complex disease. The OMERACT SjD Working Group held its first international collaborative hybrid meeting in 2023, applying the OMERACT 2.2 filter toward identification of core domains. We accomplished our first goal, a scoping literature review that was presented at the Special Interest Group held in May 2023. Building on the domains identified in the scoping review, we uniquely deployed multidisciplinary experts as part of our collaborative team to generate a provisional domain list that captures SjD heterogeneity.

BACKGROUND: Eye lesions, occur in nearly half of patients with Behçet's Disease (BD), can lead to irreversible damage and vision loss; however, limited studies are available on identifying risk factors for the development of vision-threatening BD (VTBD). Using an Egyptian college of rheumatology (ECR)-BD, a national cohort of BD patients, we examined the performance of machine-learning (ML) models in predicting VTBD compared to logistic regression (LR) analysis. We identified the risk factors for the development of VTBD. METHODS: Patients with complete ocular data were included. VTBD was determined by the presence of any retinal disease, optic nerve involvement, or occurrence of blindness. Various ML-models were developed and examined for VTBD prediction. The Shapley additive explanation value was used for the interpretability of the predictors. RESULTS: A total of 1094 BD patients [71.5% were men, mean ± SD age 36.1 ± 10 years] were included. 549 (50.2%) individuals had VTBD. Extreme Gradient Boosting was the best-performing ML model (AUROC 0.85, 95% CI 0.81, 0.90) compared with logistic regression (AUROC 0.64, 95%CI 0.58, 0.71). Higher disease activity, thrombocytosis, ever smoking, and daily steroid dose were the top factors associated with VTBD. CONCLUSIONS: Using information obtained in the clinical settings, the Extreme Gradient Boosting identified patients at higher risk of VTBD better than the conventional statistical method. Further longitudinal studies to evaluate the clinical utility of the proposed prediction model are needed.

To depict the spectrum of rheumatoid arthritis (RA) in Egypt in relation to other universal studies to provide broad-based characteristics to this particular population. This work included 10,364 adult RA patients from 26 specialized Egyptian rheumatology centers representing 22 major cities all over the country. The demographic and clinical features as well as therapeutic data were assessed. The mean age of the patients was 44.8 ± 11.7 years, disease duration 6.4 ± 6 years, and age at onset 38.4 ± 11.6 years; 209 (2%) were juvenile-onset. They were 8750 females and 1614 males (F:M 5.4:1). 8% were diabetic and 11.5% hypertensive. Their disease activity score (DAS28) was 4.4 ± 1.4 and health assessment questionnaire (HAQ) 0.95 ± 0.64. The rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) were positive in 73.7% and 66.7% respectively. Methotrexate was the most used treatment (78%) followed by hydroxychloroquine (73.7%) and steroids (71.3%). Biologic therapy was received by 11.6% with a significantly higher frequency by males vs females (15.7% vs 10.9%, p = 0.001). The least age at onset, F:M, RF and anti-CCP positivity were present in Upper Egypt (p < 0.0001), while the highest DAS28 was reported in Canal cities and Sinai (p < 0.0001). The HAQ was significantly increased in Upper Egypt with the least disability in Canal cities and Sinai (p = 0.001). Biologic therapy intake was higher in Lower Egypt followed by the Capital (p < 0.0001). The spectrum of RA phenotype in Egypt is variable across the country with an increasing shift in the F:M ratio. The age at onset was lower than in other countries.

BACKGROUND: Metabolic syndrome (MetS) is characterized by insulin resistance, high blood pressure/ sugar, dyslipidemia, and obesity. Whether MetS and its components affect the development of Behçet's Disease (BD) remains unclear. AIMS: The aim was to determine the frequency of MetS among BD patients and to study its relationship with disease characteristics. METHODS: The study included 1028 adult BD patients recruited from 18 specialized rheumatology centers. 51 healthy matched control were considered. Behçet Disease Current Activity Form (BDCAF) and the BD damage index (BDI) were estimated. Adult Treatment Panel-III criteria were used to define MetS. RESULTS: The mean age of patients was 36.8 ± 10.1 years, M:F 2.7:1 and disease duration 7.01 ± 5.2 years. Their mean BDCAF was 5.1 ± 4.6 and BDI 5.5 ± 2.8. MetS was present in 22.8% of patients and in 5.9% of control (3.9 fold higher-risk). Patients with MetS had a significantly increased age at onset (31.8 ± 9.2 vs. 29 ± 8.5 years) and higher frequency of genital ulcers (96.2% vs. 79.7%), skin involvement (73.1% vs. 50.4%), arthritis (48.3% vs. 29.1%) (p<0.0001) and CNS manifestations (18.8% vs. 13%) (p=0.042) compared to those without it. Eye involvement was significantly increased in those with MetS (82.1% vs. 74.2%) (p=0.003) with increased frequency of posterior uveitis (67.1% vs. 43.5%), retinal vessel occlusion (35.9% vs. 21.3%), retinal vasculitis (41.9% vs. 26.4%) (p<0.0001) and vitritis (37.2% vs. 24%) (p=0.001). BDCAF was significantly lower (3.9 ± 4.3 vs. 5.6 ± 4.6) and BDI higher (7.4 ± 2.7vs5 ± 2.6) (p<0.0001). CONCLUSION: BD patients with MetS are predisposed to mucocutaneous, musculoskeletal, neuropsychiatric and ocular manifestations with consequently increased damage. The involvement of the deeper structures of the eye should alarm rheumatologists to keep in mind that all patients should have an eye examination, especially those with MetS.

OBJECTIVE: We investigated prolonged COVID-19 symptom duration, defined as lasting 28 days or longer, among people with systemic autoimmune rheumatic diseases (SARDs). METHODS: We analysed data from the COVID-19 Global Rheumatology Alliance Vaccine Survey (2 April 2021-15 October 2021) to identify people with SARDs reporting test-confirmed COVID-19. Participants reported COVID-19 severity and symptom duration, sociodemographics and clinical characteristics. We reported the proportion experiencing prolonged symptom duration and investigated associations with baseline characteristics using logistic regression. RESULTS: We identified 441 respondents with SARDs and COVID-19 (mean age 48.2 years, 83.7% female, 39.5% rheumatoid arthritis). The median COVID-19 symptom duration was 15 days (IQR 7, 25). Overall, 107 (24.2%) respondents had prolonged symptom duration (≥28 days); 42/429 (9.8%) reported symptoms lasting ≥90 days. Factors associated with higher odds of prolonged symptom duration included: hospitalisation for COVID-19 vs not hospitalised and mild acute symptoms (age-adjusted OR (aOR) 6.49, 95% CI 3.03 to 14.1), comorbidity count (aOR 1.11 per comorbidity, 95% CI 1.02 to 1.21) and osteoarthritis (aOR 2.11, 95% CI 1.01 to 4.27). COVID-19 onset in 2021 vs June 2020 or earlier was associated with lower odds of prolonged symptom duration (aOR 0.42, 95% CI 0.21 to 0.81). CONCLUSION: Most people with SARDs had complete symptom resolution by day 15 after COVID-19 onset. However, about 1 in 4 experienced COVID-19 symptom duration 28 days or longer; 1 in 10 experienced symptoms 90 days or longer. Future studies are needed to investigate the possible relationships between immunomodulating medications, SARD type/flare, vaccine doses and novel viral variants with prolonged COVID-19 symptoms and other postacute sequelae of COVID-19 among people with SARDs.

BACKGROUND: Salivary gland ultrasound (SGUS) is a reliable technique for assessing the salivary glands in patients with primary Sjögren's syndrome (SS); however, the role of SGUS for diagnosis of secondary SS (sSS) in patients with systemic lupus erythematosus (SLE) was not examined. OBJECTIVE: To assess the diagnostic value of SGUS for sSS in patients with SLE, and to investigate the relationship between SGUS findings with clinical and laboratory characteristics of patients with SLE. PATIENTS AND METHODS: This cross-sectional study included 49 patients with SLE. The diagnosis of sSS was confirmed according to the 2016 ACR/EULAR criteria. Salivary gland US was performed for all patients and graded using a validated Hocevar scoring system. A complete clinical and laboratory workup for SLE was assessed. Schirmer's test and the ocular staining were performed. RESULTS: Of the 49 patients with a mean age of 30.2 ± 9.6 years, 98% were female. 19 (38.8%) had sSS. SGUS changes consistent with sSS (≥17) were found in 29 (59.2%) of the patients. Patients with higher SGUS score had more sicca findings as well as positive anti-Ro, anti-La antibodies, and poorer psychological stress (p < 0.05). The SGUS (≥17) showed a sensitivity of 84.2% and a specificity of 56.7% for sSS diagnosis, with an area under the curve of 0.77 (95% CI: 0.63, 0.91). CONCLUSION: We propose salivary gland ultrasound as a non-invasive method in the diagnostic workup for sSS in patients with SLE. Further studies to confirm the diagnostic value of SGUS in a larger sample of patients with sSS will be necessary.

Imaging has long been taking its place in the diagnosis, monitor, and prognosis of rheumatic diseases. It plays a vital role in the appraisal of treatment. Key progress in the clinical practice of rheumatology is the innovation of advanced imaging modalities; such as musculoskeletal ultrasound (MSUS), computerized tomography (CT) and magnetic resonance imaging (MRI). These modalities introduced a promising noninvasive method for visualizing bone and soft tissues to enable an improved diagnosis. The use of MSUS in rheumatology is considered a landmark in the evolution of the specialty and its ease of use and many applications in rheumatic diseases make it a forerunner instrument in the practice. The use of MSUS among rheumatologists must parallel the development rate of the excellence revealed in the specialty. Moreover, innovative interventional imaging in rheumatology (III-R) is gaining fame and key roles in the near future for a comprehensive management of rheumatic diseases with precision. This review article throws light on the emergence of these robust innovations that may reshape the guidelines and practice in rheumatology, in particular, efforts to enhance best practice during the coronavirus disease 2019 (COVID-19) pandemic are endorsed.
RESUMEN
The study aimed to explore the experience of coronavirus disease-2019 (COVID-19) infection and vaccine adverse events (AEs) among rheumatologists. A validated questionnaire was distributed as a Google form to rheumatologists across the country via social networking sites from late December 2021 till early January 2022. The questionnaire included questions regarding participants' socio-demographic details, COVID-19 infection and vaccination details with special emphasis on AEs. Out of 246 responses, 228 were valid. 200 (81.3%) responders had received the vaccine. The mean age of the 228 participants was 37.9 ± 8.5 years, 196 were females and 32 males (F:M 6.1:1) from 18 governorates across the country. Comorbidities were present in 54 subjects (27%). There was a history of highly suspicious or confirmed COVID-19 infection in 66.7% that were all managed at home. The COVID-19 vaccine was received by 200 and a booster dose of 18.5%. Obesity and musculoskeletal involvement co-morbidities were present only in those with AEs (9.1% and 5.5% respectively). AEs were present in 82%; 66.7% had injection-site tenderness, 50% fatigue, 35.5% fever, 15% chills, 42.5% myalgia, 14.5% arthralgia, 8% low back pain, headache 31%, dizziness 10%, sleepliness 16% and 15% developed post-vaccine. There were no differences according to the geolocation regarding the occurrence of COVID-19 infection (p = 0.19) or AEs post-vaccine (p = 0.58). The adverse events were mostly mild to moderate and tolerable which makes this work in agreement with other studies that support the broad safety of the vaccine in favor of the global benefit from mass vaccination.

OBJECTIVE: To characterize 414 patients with primary SS who developed haematological malignancies and to analyse how the main SS- and lymphoma-related features can modify the presentation patterns and outcomes. METHODS: By January 2021, the Big Data Sjögren Project Consortium database included 11 966 patients fulfilling the 2002/2016 classification criteria. Haematological malignancies diagnosed according to the World Health Organization (WHO) classification were retrospectively identified. RESULTS: There were 414 patients (355 women, mean age 57 years) with haematological malignancies (in 43, malignancy preceded at least one year the SS diagnosis). A total of 376 (91%) patients had mature B-cell malignancy, nearly half had extranodal marginal zone lymphoma (MZL) of mucosa-associated lymphoid tissue (MALT lymphoma) (n = 197), followed by diffuse large B-cell lymphoma (DLBCL) (n = 67), nodal MZL lymphoma (n = 29), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) (n = 19) and follicular lymphoma (FL) (n = 17). Rates of complete response, relapses and death were 80%, 34% and 13%, respectively, with a 5-year survival rate of 86.5% after a mean follow-up of 8 years. There were significant differences in age at diagnosis (younger in MALT, older in CLL/SLL), predominant clinical presentation (glandular enlargement in MALT lymphoma, peripheral lymphadenopathy in nodal MZL and FL, constitutional symptoms in DLBCL, incidental diagnosis in CLL/SLL), therapeutic response (higher in MALT lymphoma, lower in DLBCL) and survival (better in MALT, nodal MZL and FL, worse in DLBCL). CONCLUSION: In the largest reported study of haematological malignancies complicating primary SS, we confirm the overwhelming predominance of B-cell lymphomas, especially MALT, with the salivary glands being the primary site of involvement. This highly-specific histopathological scenario is linked with the overall good prognosis with a 5-year survival rate of nearly 90%.

PURPOSE: To assess vitamin D receptor (VDR) gene polymorphisms and bone mineral density and to investigate the possible risk factors of osteoporosis and fracture in rheumatoid arthritis (RA). METHODS: A total of 97 RA patients and 45 matched controls were enrolled. Serum vitamin D level, VDR genotyping, dual-energy X-ray absorptiometry (DEXA) scan, trabecular bone score (TBS), and fracture risk assessment (FRAX) in 10 years were assessed. Disease activity score (DAS28) and modified health assessment questionnaire (MHAQ) were measured. RESULTS: The mean age of the patients was 47.9 ± 8.9 years; 85 females, 12 males (F:M 7.1:1) and mean disease duration 9.4 ± 6.2 years. DAS28 was 4.52 ± 1.04 and MHAQ 0.6 ± 0.4. There was a significant difference between cases and controls as regards DEXA and FRAX (p < 0.0001) but the TBS and VDR genotyping were comparable (p = 0.29 and p = 0.12, respectively). The vitamin D level was comparable with the control (9.3 ± 6.5 vs 10.4 ± 7.5 ng/mL, p = 0.4). None of the patients was receiving anti-osteoporotic therapy or biologic therapy. There was a significant association between the presence of osteoporosis and age, disease duration, menopause, and rheumatoid factor (RF) positivity. The TBS was significantly lower and FRAX higher in patients with positive RF and anti-CCP. FRAX was significantly related and the TBS inversely with the age, disease duration, serum uric acid, alkaline phosphatase, and MHAQ. CONCLUSIONS: Reduced BMD and increased tendency to fractures are remarkable in RA patients. Vitamin D level was decreased in patients and control, and VDR gene polymorphisms were not linked to RA. TBS and FRAX are effective tools to assess osteoporotic fractures in RA. Key Points ⢠Reduced bone mineral density (BMD) and increased tendency to fractures are remarkable in rheumatoid arthritis (RA) patients. ⢠Vitamin D level was decreased in patients and control, and VDR gene polymorphisms were not linked to RA. ⢠Trabecular bone score (TBS) and fracture risk assessment (FRAX) in 10 years are effective tools to assess osteoporotic fractures in RA.

OBJECTIVE: The aim of the work was to delineate the computed tomography pulmonary angiography (CTPA) findings in Behçet's disease (BD) patients with and without chest manifestations. PATIENTS AND METHODS: The study included 122 BD adults recruited from 5 Teaching University Hospitals in Egypt of those who agreed to perform a CTPA. The Arabic version of BD current activity form (BDCAF) and BD damage index (BDI) were assessed. Detailed pulmonary manifestations, examination, plain radiology chest, and CTPA findings were recorded. RESULTS: The mean age of patients was 36.9 ± 11.3 years, male:female was 1.8:1, disease duration 9.6 ± 8.2 years, and age at onset 28.3 ± 8.6 years. Their mean BDCAF was 4.4 ± 2.2 and BDI 3.4 ± 1.8. There were chest manifestations in 51 (41.8%) and plain chest x-ray findings in 13 (10.7%) and CTPA findings in 31 (25.4%) in the form of pulmonary thromboembolism in 15 (12.3%), pulmonary aneurysms in 7 (5.7%), pneumonia in 5 (4.1%), interstitial lung disease in 4 (3.3%) and pleural effusion in 3 (2.5%). Patients with chest manifestations had significantly higher frequency of cardiac manifestations (15.7%) compared to those without (2.8%; p = 0.023); chest x-ray findings tended to be higher (17.6% vs 5.6%; p = 0.05) while CTPA findings were significantly detected (51% vs 7%; p < 0.0001). Higher frequency of CTPA findings were in females (p < 0.0001). Yet the rate of serious pulmonary embolisms, aneurysms, and thrombosis was exclusive in males. CONCLUSION: Meticulous investigation of the chest manifestations is warranted in BD patients to undermine the actual magnitude of pulmonary impact. CTPA provides a realistic estimate of the extent of involvement even in asymptomatic cases. Key Points ⢠Meticulous chest assessment is warranted in Behçet's disease patients to undermine the actual magnitude of pulmonary impact ⢠CTPA provides a realistic estimate of the extent of involvement even in asymptomatic cases.

OBJECTIVES: Several studies have shown associations of ABO and Rh blood groups with various diseases; however, the relationship of ABO and Rh blood groups with rheumatic diseases are scarce. The aim of the present study was to examine whether there is an association between ABO and Rh blood groups and the types of rheumatic diseases. METHOD: In this multi-centre cross-sectional study, sociodemographic data, type of rheumatic disease, and type ABO and Rh blood groups were examined for patients with different rheumatic diseases. RESULTS: A total of 304 patients; 207 (68.1%) were diagnosed with rheumatoid arthritis, and 40 (13.2%) had systemic lupus erythematosus. The patients were assessed for blood types; 37.8% patients had A type, 27.6% had B type, 19.1% had O type, and 15.4% had AB type. The Rh (+) blood group was more prevalent (89.1%) than Rh (-). Blood group A was more prevalent in patients with rheumatic disease, followed by B, O, and AB respectively, although there was no significant difference in the distribution of ABO groups among rheumatic diseases. Female gender, smoking, and anti-cyclic citrullinated peptide are significantly different between the blood groups within rheumatic diseases. CONCLUSION: The A and Rh (+) blood groups were more commonly observed in patients with rheumatic diseases. There was lack of association between types of rheumatic diseases and ABO blood groups. The study provides knowledge for the interaction between ABO blood groups and several risk factors related to rheumatic diseases and may serve a guide for future clinical studies.
RESUMEN
OBJECTIVE: To examine the potential therapeutic effect of mesenchymal stem cells (MSCs) for experimental scleroderma. MATERIALS AND METHODS: Fifty-four mice six-week-old (30-35 g) were studied. Hypochlorous acid (HOCl) induced scleroderma was considered. Mice were divided into 3 groups: (I) Control: Six mice did not receive any treatment and were sacrificed at the end of the experiment; (II) HOCl mice (induced scleroderma as a positive control): (III) MSCs-treated HOCl mice: Thirty six HOCl-induced mice were injected with MSCs (7.5 × 105) intravenous every week for 3 weeks. Skin pieces were taken from the backs of mice and lung tissue pieces. a smooth muscle actin (α-SMA) and transforming growth factor-ß (TGF-ß1) were analysed or fixed in 10 % formalin for skin and lung tissue histopathological analysis. Plasma nitric oxide (NO) was also assayed. RESULTS: There was a significant rise in the NO level and of the cutaneous and lung tissue α-SMA and TGF-ß1 in untreated scleroderma-induced mice. The values significantly normalized after MSC therapy over the 7 weeks duration of the study. The altered histopathology of the skin and lung tissues in the scleroderma-induced mice showed a remarkable tendency to normalization of the skin and lung parenchyma and vasculature. CONCLUSION: There was a significant rise in the level of NO and skin and lung tissue α-SMA and TGF-ß1 in untreated scleroderma-induced mice and values were significantly normalized after MSC therapy over the 7 weeks duration of the study. Altered histopathology of the skin and lung appeared nearly normal after MSC therapy.

BACKGROUND: We describe the early experiences of adults with systemic rheumatic disease who received the COVID-19 vaccine. METHODS: From 2 April to 30 April 2021, we conducted an online, international survey of adults with systemic rheumatic disease who received COVID-19 vaccination. We collected patient-reported data on clinician communication, beliefs and intent about discontinuing disease-modifying antirheumatic drugs (DMARDs) around the time of vaccination, and patient-reported adverse events after vaccination. RESULTS: We analysed 2860 adults with systemic rheumatic diseases who received COVID-19 vaccination (mean age 55.3 years, 86.7% female, 86.3% white). Types of COVID-19 vaccines were Pfizer-BioNTech (53.2%), Oxford/AstraZeneca (22.6%), Moderna (21.3%), Janssen/Johnson & Johnson (1.7%) and others (1.2%). The most common rheumatic disease was rheumatoid arthritis (42.3%), and 81.2% of respondents were on a DMARD. The majority (81.9%) reported communicating with clinicians about vaccination. Most (66.9%) were willing to temporarily discontinue DMARDs to improve vaccine efficacy, although many (44.3%) were concerned about rheumatic disease flares. After vaccination, the most reported patient-reported adverse events were fatigue/somnolence (33.4%), headache (27.7%), muscle/joint pains (22.8%) and fever/chills (19.9%). Rheumatic disease flares that required medication changes occurred in 4.6%. CONCLUSION: Among adults with systemic rheumatic disease who received COVID-19 vaccination, patient-reported adverse events were typical of those reported in the general population. Most patients were willing to temporarily discontinue DMARDs to improve vaccine efficacy. The relatively low frequency of rheumatic disease flare requiring medications was reassuring.

OBJECTIVES: This study aims to present the manifestations of juvenile systemic lupus erythematosus (JSLE) across Egypt, to focus on age at onset and gender-driven influence on disease characteristics, and to compare findings to other countries. METHODS: The study included 404 Egyptian children with systemic lupus erythematosus (SLE) presenting to one of the specialized rheumatology centers corresponding to 13 major governorates. Juvenile cases age was ≤ 16°years at the time of recruitment. The SLE Disease Activity Index (SLEDAI) and damage index (DI) were assessed. RESULTS: The mean age was 13.2 ± 2.4°years; 355 females and 49 males (7.2:1), and the disease duration was 2.3 ± 1.6 years, while age at disease onset was 11.1 ± 2.5°years. Their SLEDAI was 13.5 ± 12.3, and DI, 0.36 ± 0.78. The overall estimated prevalence of childhood-SLE patients in the recruited cohort in Egypt was 1/100,000 population (0.24/100000 males and 1.8/100000 females). 7.4% developed pre-pubertal SLE (≤ 7 years); 73.3%, peri-pubertal; and 19.3% during early adolescence. The differences according to age group were equal for gender and clinical manifestations except skin lesions present in 59.3% of pre-pubertal onset, 74.6% of peri-pubertal, and 84.2% of adolescents (p = 0.029), and renal involvement in 73.8% of peripubertal, 62.1% of pre-pubertal and 58.9% of adolescents (p = 0.03). Laboratory investigations, SLEDAI, and DI were similar among age categories. Lupus nephritis was more common in Egypt compared to JSLE from other countries. CONCLUSION: Our large multicenter study identified that female gender influenced disease characteristics with more frequent skin involvement. Skin lesions were significantly higher in adolescents, while renal involvement in peri-pubertal children.

BACKGROUND: Behçet's disease (BD) is a chronic multisystem variable vessel vasculitis. Disease damage is irreversible and permanent. Validated tools evaluating damage are limited. Enhancements in the clinical treatment of vasculitis will take place from the development of refined and exclusive indices for individual vasculitic syndromes including BD and attempting their international validation. OBJECTIVES: This aim was to develop and validate a simple BD Damage Index (BDI). METHODS: This was a nationwide study including 1252 BD patients. The work consisted of 3 stages. Stage 1: items generation for score content. Stage 2: items selection for the draft score was performed by an expert rheumatologist. Stage 3: the content validity of the draft score was assessed and BDI, Vasculitis Damage Index (VDI), Antineutrophil cytoplasmic antibody-associated Vasculitis Index of Damage (AVID) and Combined Damage Assessment Index (CDAI) were calculated and compared. RESULTS: The mean age of the BD patients was 36.1 ± 9.9 years. Stages 1 and 2 resulted in a BDI instrument containing 73 items with a maximum score of 100. Stage 3, the VDI, CDAI, AVID, and BDI were 2.9 ± 2.2, 3.1 ± 2.3, 3.1 ± 2.3 and 5.1 ± 2.9, respectively. High correlations (r = .9) between comparable damage scores assured acceptable concurrent validity. CONCLUSION: The proposed BDI represents a new robust and potentially useful tool when dealing with BD chronic status.

OBJECTIVES: The aim of the present work was to explore the perspectives of Egyptian Rheumatology staff members as regards the coronavirus disease-19 (COVID-19) vaccine. METHODS: The survey is composed of 25 questions. Some questions were adapted from the global rheumatology alliance COVID-19 survey for patients. RESULTS: 187 rheumatology staff members across Egypt from 18 universities and authorizations actively participated with a valid response. The mean time needed to complete the survey was 17.7 ± 13 min. Participants were 159 (85%) females (F:M 5.7:1). One-third agreed that they will be vaccinated once available, 24.6% have already received at least one dose, 29.4% are unsure while 16% will not take it. Furthermore, 70.1% agreed that they will recommend it to the rheumatic diseases (RD) patients once available, 24.1% are not sure while 5.9% will not recommend it. RD priority to be vaccinated against COVID-19 in descending order include SLE (82.9%), RA (55.1%), vasculitis (51.3%), systemic sclerosis (39.6%), MCTD (31.6%), Behcet's disease (28.3%). The most common drugs to be avoided before vaccination included biologics (71.7%), DMARDs (44.4%), biosimilars (26.7%), IVIg (17.1%) and NSAIDs (9.1%). CONCLUSIONS: The results of the study and specifically the low rate of acceptability are alarming to Egyptian health authorities and should stir further interventions to reduce the levels of vaccine hesitancy. As rheumatic disease patients in Egypt were not systematically provided with the vaccine till present, making the vaccine available could as well enhance vaccine acceptance. Further studies to investigate any possible side effects, on a large scale of RD patients are warranted.

BACKGROUND: Behçet's disease (BD), commonly seen in the Silk road countries, is a variable vessel vasculitis with no specific investigation that reflects disease activity. The Behçet's Disease Current Activity Form (BDCAF) is the most famous and acceptable clinical activity score. PURPOSE: To develop a cross-cultural adaptation of the BDCAF to the Arabic language (Ar-BDCAF)-Egyptian dialect-across the country and to consider preliminary evaluation of its reliability in assessment of BD activity. PATIENTS AND METHODS: The score was translated to Arabic language and revised by 3 rheumatology consultants. Reliability of Ar-BDCAF was tested among 88 BD patients from 9 Egyptian main city centers. Patients were questioned by two specialists at 30 min interval to evaluate inter-observer rating and twice by the same physician within 24 h to assess the intra-observer rating. RESULTS: Patients were 64 males and 24 females (2.7:1) with a mean age of 35 ± 10.3 years. The average time required by the consultant to fill in the form was 5.1 ± 2.2 min (1.5-15 min). The mean Ar-BDCAF scores were 9.81 ± 6.22 (0-25) and 9.53 ± 6.13 (0-28) with an intra-observer concordance (p = 0.28) and was 9.95 ± 6.47 (0-29) for the inter-observer rating (p = 0.89 and p = 0.66, respectively). CONCLUSION: The Ar-BDCAF is a measurable, easy to calculate, and reliable index for assessing disease activity in Egyptian BD. The Ar-BDCAF score can be used in daily clinical practice to assess BD activity and its use can be extended to other Arab countries for possible regional validation and adaptations. Key Points ⢠The Arabic version of the BDCAF can be extended to other Arab countries for development of a Pan-Arab score. ⢠This is the first study to provide a reliable and valid Arabic version of the BDCAF-Egyptian dialect for measuring current disease activity in BD patients.
